Ok well If i get a PowerMac G5 Dual 2 GHz will there be anything that I should upgrade or change, other than the computer is there any software that you reccomend that I buy. To me the specs of the Mac all seem very high perfromance except the RAM - 512MB of 533MHz DDR2 SDRAM (PC2-4200), is there something special/better about this ram than the one in a normal PC because most computer I am seeing have a 1 Gb, is there something better about this RAM or is it worth getting some more RAM?
